Indicates that a unitdata request issued by the application could not be delivered, either by the local SCCP layer or by the remote layer (a UDTS or XUDTS message was returned). This status indication is returned only if the message handling options in the original unitdata request (protoClass.msgHandling) specified the message return (MSG_RETURN) option. The SCCPSTAIND event returns a data structure of type SccpUdataRqst.
